T o all lw/iom it may conce'm:

Be it known that I, Fiuusiucii A. HAirr, a citizen of tlie United States, residing in Newark, in the county of Essex and State of New Jerse have invented certain new and useful mprovements' in Combined Typewriting and Computing Machines, of which the following is a specification.

My invention relates to computing machines, and is herein disclosed as applied to an Underwood-Hanson combined typewriting and computing `machine in which the, numeral keys of the typewriter sct up numbers on computation members, and these nu'mbers are later carried into computing or adding wheels.

My invention is designed to be used with computing machines in which there are several adding lieads or totalizers, and therefore I have herein shown it as applied to an Underwood-Hanson, machine havingr two gangs of computing wheels. Such combined typewriting and 4computing machines are often used for doing either several varieties of work, or else work which requires totalizei's to be in use in some writ-ing zones at one time and in other zones at another time. It has been found, howeveccthat in the hands of the ordinary operative or ty iist, the'scparate settings of the connections to the dif'- ferent totalizers are troublesome. because they involve the setting of unfamiliar types of parts to control unifamiliai` niechanialil combinations, and therefore. the setting otsuch parts is disconcerting to the average person into whose handsl such machine is likely to be placed for use.

In some combined typewrting and computingmachines the zones of computation are selected either by denomination selectors directly, or by devices controlling such denomination selectors. I have found it advantageous to provide a handleor fingerpiece of a familiar type which the operative of such a combined typewriting and com puting machine muy adjust in any one,of several positions, with the result thatin one position the finger-piece will make certain denomination selectors effective or ineffective and in another iosition may be effective in an entirely di erent manner, so that either the same enomination selectors, or some of them,may be made effective where they were ineffective before, and vice versa, or other selectors may be made effective or ineffective. i

I have disclosed this invention, as intimated above, on a combined t pewritin and computing machine ofthe nderwoo Hanson type, such as is shown in my prior application, Serial No. 466,836, filed Dcceniber 10, 1908 (now Patent No. 1,270,411, of June 25, 1918), and in this machine I have found it simplest to effect the silencing by setting the denomination selectors themselves at ineffective positions. Utlier features and advantages will hereinafter appear.

In the accompanying drawings,

In the usual Underwood-Hilison combined typewriting 'and computing machine, alphabet keys' 1 and numeral keys 2, depress ke -levers 3, so thatll sub-levers 4 connected t iereto swingtype-bars 5 upwardly and rearwardly, with the result that types on said 4t pe-bars'print against the front face of a p aten 7., said platen forminor art of theusual traveling carriage 8. iV ienever any alphabet key 1 or numeral key 2 is depressed, the actuated type-bar strikes a segmental universal bar 9, causing said universal bar to vibrate the usual typewriter feeding dogs 10, said dogs permitting sys the carriage 8 to be drawn along a step at a time at ever key stroke in the usual manner, said ogs accomplishing this by their alternate engagement with the escapement wheel 11 which isconnected to the usual pinion 12, meshing with the usual rack bar 13, said rack bar ,being connected to the typewriter carriage. The carriage is drawn along in this manner, because it is constantly under tension of the usual spring barrel (not shown herein).

Whenever a numeral key 2 is depressed within the computing zone, it not only feeds the carriage 8 along a step, but it also sets up on a computation bar the digit which is being printed at the moment, and after all the di Vits of a number have been so set up, the igits are carried into a register comprising computingr or adding wheels 14 in the usual manner. To bring about this setting up of digits, the typewritercarriage is provided with a denomination selector 15 in the form of a pivoted lever or camming tappet, which is adapted to ride senkt/tim under a series of jacks 16 in a casing forming a head, as the typewriter travels along, and cause said jacks to raise pin-bearing com utation members 17 within the range o pin-setting bars 18, one of which is actuated every time its numeral key 2 is depressed. The pin-'bearing bars 17 normally hold their pins 19 beneath and out of range of the pin-setting bars 18, but whenever the typewriter carriage enters a computing zone, the'dog or tappet 15 rides under a jack 16 and causes that jack, by means of the usual connections, to raise its in-bar 17 so that the pins 19 thereon will e within ran e of the pin-setting bars 18.

If a numera key is depressedA in the addingzone, its pin-setting bar 18 swings downwardl and de resses its pin 19,0n the bar 17 which is at t e moment raised by the dog 1,5, with the resultv that the depressed in projects its lower end beneath the pin ar 17. As the typewriter key rises, the typewriter carriage feeds along one space, dropping the pin bar 17 on which t e pin has )ust been set, and raises another pin bar to the pin-setting level, a key depression' again setting a pin, and so on.

When the series 'of pins have thus been set up, representing all the digits of a number, the number represented by them is carried into the computing wheels 14 by means ofa general operator, which includes a cross bar 20 and side bars 21. 7The cross b ar 20 pinion 23 which is connected in the usual manner by means of a pawl-and-ratcliet to its computing wheel 14. The general operator may be actuated by the usual segment 24 and idle pinion 25.

On its return stroke the general operator brings back the pin bars 17 to their normal position, so that the pins 19 s'tand beneath their setting bars 18, and at the very end of the return stroke all of the depressed pins are restored by means of the usual pin-restoring plate 25". v

The connections between the jacks 16 and the pin bars 17y include the usual wires 26,

which extend downwardly lbehind the pivotrod 27 on which thefjacks l'are 'ournaled, said wires engaging the rear en of bellcranks 27, said ell-cranks at their forward ends engaging the` usual linka es 28, forming a transposition device, so t at each jack 16 operatesonly its ownpin bar 17.

If it is desired to subtract, the operative may press a subtraction liandle29 to thrust rearwardly thel usual subtraction bar 30, thus altering the cnnectionsin such a way that the mechanism willperform Acomplementary subtraction in the manner set forth in the co-pending l application, Serial No. 626,550, filed May 11,1911, (now Patent No. 1,278,812, dated ,September 10, 1918.) The method by "which subtraction is done forms no art of the present :,inrention, -and will not t erefore be described in .any further detail. It may be noted, however, that to avoid confusing the Vtyipist allftheactive registers add when any a ds, ones subtract when any subtracts.

The said machine is'herein illustrated as adapted to either add or subtract in any one of several columns, and is further illustrated as adapted to have the computing devices selectively silenced in any column. The machine, in addition, is provided withthe usual s'ilencing rolls 32, each of which is adapted to support the tappets 15, when adjacent the jacks 16, said tappets being normally beneath and clear of the jacks 16. This may be accomplished in' the usual manner b mounting the tappets on `blocks 33 whic are pivoted on the usual rod 34,lr reduced at its end 34, to allow insertion and removal of blocks 33, and the blocks 133 are provided with the usual teeth 35 for engaging the usual rack bar 36.v l

In the normal operation of the machine, each block 33 is normally dropped down, so that its body rests on the rod 36, thus holding its ta pet 15 clear of the acks and therefore in ective. f In. the adding zone, how'- ever, each block rides up on the silencing roll 32, and holds Aits tappet 15, so that its path will carry it across the jacks 16 and raise them seratim. Either roll 32, how- Y ever, mal be manually silenced by means of its usua ,handle 37, one oi which is proand the active y vided oneach side near the front of the machine, and is connected by meansof a link 38 to a long bell-crank 39, said bell-crank having an arm 40 which is adapted to rock the si encing roll 32 outward to a position clear of the blocks 33, said arm 40 accomplishing this by means of a rock arm 41 fast on the shaft 42, which carries the silencing roll 32, said .roll bein pivoted in arms 43 fast on said shaft. Tie handle 3T may be latched so as to hold the roll 32 outward by catchin the handle in an L 44 of an elongated s ot 45.

Ordinarily there are only one or two handles ,37, which respectively control either of the silencing rolls 32, or else each of which controls half the silencing rolls 32, if the machine has more than two registers. In order'to provide means for selectively silencing the tappets 15, I have provided an auxiliary silencing meansl adapted to selectively be effective on the tappets 15, even when the tappets are held in upward effective position by the silencing 1'oll`s 32. For this purpose, the tappets 15, as best shown in Fig. 5, are pivoted in the usual manner on -their blocks 33 by means of pivots 46 in the blocks 33. The taprpets 15 are so shaped that while they are able to swing freely during the return movement of the carriage, they are held in upright position during the forward traveling movement thereof. For this purposeeach tappet 15 is provided with the usual flat face 47, which, during the traveling movement of the carriage, lies flat against a wall 48 of its block 33, the tappet 15 being, normally held in such position by means of a lightspring 49. During the return movementof the typewriter carriage, however, the tappet can swing freely toa'ide over the' jacksbecausev there isjn wall of the block 33 to prevent it from swinging out practically horizontal, and because its spring 49 is ve light.

In order to se ectlvely make the tappets 15 inell'ectivef, I have found it possible to provide a se arate silencing member or lever for an esired tappet 15 which is adapted to roc its tappet over into its'horizontal position, and thereby hold it free from the Jacks with which it would normally engage during its traveling movement. These levers, as seen in Fi 4, may be oftwo forms, one of which is s own at 50, adjacent the head ofv jacks marked No. 3, and said lever is pivoted intermediate its ends near the rear end of the block 33, and ,is provided with a tail 51, which has a pin-and-slot connection 51'with a radial pin 52, ro-

jecting vfrom a manually controlled adjustin rod 53. The pin 52 is mounted on a colar which is secured to the rod 53 by a set screw 76. It will be obvious that by i shifting the rod 53, the lever 50 may either be entirely ineffective, or may be swung over its tappet 15, in such a way as to swin said tappet downward to the left, and hold it clear of the jacks in the head Na 3. In this way the silencing of said tappet is entirely independent of the silencing roll 32 for that head, vand if said silencing roll is always effective, the tappet 15 shown at jack-head Nd 3 may be individually controlled in any manner the operative may prefer,

At the jack-head Na l is shown a tappet 15,-which is under the control of a silencinfr lever 54, of a somewhat different type, said lever 54 being pivoted on its block 33 toward the rear end of said block, and being short compared with the lever 5U. (In the present machine, register and jack-head Na 2 areomitted.) This lever 54 is controlled by the rod 53 by means of a pinand-slot connection 55,' similar to the pin-and-slot connection 51, but is controlled indirectly by said vconnnection, this being so because said connection 55 is effective on an intermediate lever 5G, having said pin-and-slot connection at one end thereof. and engaging the iever 54 at the opposite end.it being pivoted intermediate these points. The re suit is .that if the rod 53 is set at the extreme right-hand position, which is illustratedin Fi .4','the tappet 15 adjacent the jack-head l\o. 3 will be silenced,\vl1ile the tappet 15 adjacent the jack-head No. 1 will have its lever 54 thrown to the farthest point (possible from its effective point. If the ro 53 is thrown to the left-hand limit of its lthrow, the lever 50 will be thrown to inetective position, whereas the lever 54 will be made effective to silence its tappet 15. This lastnamed condition is illustrated in selectively'eiective and ineffective. In the present embodiment the rod 53 is shown as controlling only two adding heads, this be.- ing found sufficient for certain bookkeeping needs, and the scale illustrated, therefore, is provided with digits 1 and 3, which are adapted to indicate, by A the pointer 58, whether the tappet associated with refrister or jack-head or that associated with 3" vis eifective, the effective tap iet being the. one on' which the selecting device is ineffective. Intermediate'this scale is the letter N to indicate that the selecting deviceis eil`ective on neither of the tappets. The rod 53 is slidably mounted in extensions 60 of the usual brackets 61 of the typewriter carriage. and is rovided with three sockets 62 which are a apted to coperate with a dentent pin 63 projecting from-a spring 6l through an openin in one of the bracket extensions. It will be understood that the detent device, just described, has the additional function of assistin in placing rod 53'in proper ,adjusted positions. In other words, the detent pin '63 in'coii'nection with the rsockets-62 insures uniform positioning of rod 53 in its three different positions for adjustment. The pin-and-slot joints 51 and 55 are allowed sufficient play to enable the blocks 33 to have all the freedom ot' vertical movement they require.

'I fhe adjusting rod 53 is provided with a collar 65 to limit its outward throw,` so that it will not escape from the brackets in which is adapted to do i tappets 15 of one set it is slidably mounted, and an enlarged hub 66 on'the handle 57 limits the throw of 'said rod in the' opposite direction.

v\'I`h'e pins of the pin-and-slot connections 51 and 55 are mounted in collars 75, which for purposes of 4manufacture are advantageously adjustable along the rod 53, and are fastened by set screws 76 in their proper positions. i

The tappets l5 may be made ineffective, if desired, individuell or any number `of them, by swinging t em up around the rod 34 on which their blocks 33 are pivoted. The lpin-nnd-slot connections 51, 55 are so desi ned to permit this to be done perfectly ree The machine herein illustrated in Fig. 6

computing in three columns, on two registers, and, for this purpose .is .provided with two sets of tappets 15, the tappets of each set being efi'ective'on onl their own jack-head, and through it on their own register. For this purpose, the as shown at 67,68 and 69, are all in a single plane, to beefective on 'ack-lugs 70 (see Fi". 4), which are set bac from theends of the' picks. The ta pets 67, 68 4and 69,. therefore as -will e determined by an inspection of? Figs. 1 and 6, will be effective only on jack-head Na 1,. The other tappets 71 72 are effective on jack-head Xin 3, ,on y, and, for this purpose are set in another plane wel-l forward from the rear ends of the blocks 33, in whiclitliey are mounted, and all lie in the planel of lugs 74, which are at the extreme front of the ends of the jacks in jack-head Na 3.

The tappcts provided in Fig. 6 are adapted to be used in'making out bills and statements according to the outline given below. This outline utilizes ahind of bill coinmonly used. in commercial transactions, and is a kind of bill which'cannot be made out 4on a machine having automatic shifts from addition to subtraction andvice versa, un-

of $25, which is t e less the automatic connections are extremely complicated.

' -The columns.

Charges. To mls. Balance.

In the column of charges there are entered items of $20, $10 andvlO. These items `are added in both registers Nos. l and 3 by the tappets 67 and 71. Both registers then show .a total of $40. The typewriter carriage is then shifted along to the column or zone for totals. Inthis column, tappet 68 and therefore, its registerfNo. 1) are made ineffective by shifting the handle-57 to the;

Fig. 7 osition, and the subtraction bar 30 made e ective; then'tlie total of $40. isprintcd, thus subtracting it out from o. 3 register by tappet 72, which remains effective. The typewriter carriage is again brought back to enter credits in this same total column, and the handle' remains at the same position, but the machine is now caused to add, and credit items of $5,$5 and $5 are therefore entered and added in register No. 3i by tappet 72, additively. The t pewriter carriage is now brought back to write in its total and credit column again, and the sum of the credit items, amounting to $15. is subtracted from both the registers;

for this purpose the subtraction bar is made effective, and the handle 57 is shifted to its Fig. 6 position, soA that both the tappets 72 and 68 are effective. The writing of the total credits will now erase said credits from the No 3 register and deduct said credits from the No. 1 register, leaving the Na 3 register at zero,ready for the next statement. No. 1 re ister now shows a-'balance total balance to be written on this bill or statement to Ycomplete the making out of it. The typewriter carriage is therefore positioned at the balance column, which makes the tappet 69 effective on the No. 1 register, and with the subtraction bar still effective, the $25 is written in the balance column, thus erasing the $25 from the Na 1 register, leaving both re isters at zero'. and the statement rv bill rea y for removal from themacliine.

The arrangement `of. registers and tappets shown in Fig. ILis one adapted for many kinds of work, such as making out insurance premium receipts, in which itemsare always 4entered in one of two columns .on` a great i never make a mistake in using a device suc i as that shown in Fig. Il;

The silencing rolls 32 therefore are usually used only for semi-permanent` adjustments, sucli for example as for a days work on a special forni, when the machine is otherwise adjusted .for more complicated forms. i
